Instructional coaching can promote more effective and engaging learning in the classroom. In this video, Kirk Walters, AIR principal researcher and instructional math coach, shows how he supports teachers and helps students learn critical math skills. Walters, whose research primarily focuses on ways to improve K-12 math teaching, examines why it’s important to teach students not only how to do mathematical procedures but also to understand the concepts behind them.

We learn how to solve exponential equations in which one side is a fraction. We use the power of -1, to get rid of the fraction and to then solve the equation in the usual way, by writing both sides of the equation as a power of the same base. The method is explained in detail by working through 3 examples.

What do you know about dinosaurs? In Dinosaur Facts for Kids, you will learn cool facts about many of these ancient animals. They lived during the Mesozoic era millions of years ago, which is divided into three smaller periods: Triassic, Jurassic, and Cretaceous. To this day, scientists still debate about the cause of their extinction. Was it because lots of volcanoes erupted at the same time? Or was it because a meteor crashed into Earth and caused a ton of damage?

Regardless, we can learn a lot about dinosaurs by studying their fossils. The first dinosaur bones ever found were found in China. The people originally thought they were the bones of giant dragons! The word dinosaur means “terrible lizard,” which works because most dinosaurs are classified as reptiles. Because of the work of paleontologists, we know that some dinosaurs walked on two legs while other walked on four. We also know that these terrible lizards varied greatly in size. Some were as small as chickens while others were bigger than a school bus!

The types of food that dinosaurs ate varied as well. Dinosaurs were either herbivores, carnivores, or omnivores, just like the animals of today. There are also some dinosaurs that are considered the ancient ancestors of birds!

We hope you and your student(s) enjoyed learning about these four different dinosaurs! If you want to learn even more, head over to our website and download one of our many free lesson plans about dinosaurs, full of activities, worksheets, and more!

This precalculus video tutorial provides a basic introduction into multiplying matrices. It explains how to tell if you can multiply two matrices together and how to determine the order of the new matrix. The order of the new matrix is based on the rows of the first matrix and the number of columns in the second matrix. To multiply two matrices together, multiply the rows of the first matrix by the columns of the second matrix and find the sum of the products. This video contains plenty of examples and practice problems on matrix multiplication.

In this video we learn all about constellations for kids. At night we can see thousands of stars and scientists long ago figured out that the stars line up in recognizable patterns. The patterns form shapes of people, animals, and mythological beings. Early astronomers called these special patterns constellations. Each star in the pattern has a name and is connected to form a different constellation. It is almost like a “connect-the-dots” picture, but instead of using numbers and dots, the twinkling stars are connected to form the special patterns. You have have heard of the Big Dipper, Orions Belt, or Aries, but these are only a few of the constellations there are many more!

Many constellations have their roots in myths. A myth is an ancient story about many different things. Constellation myths are usually stories about gods, heroes and creatures such
as serpents, dragons, flying horses and more. The images related to these myths are formed using connected stars. The Greeks and Romans created the stories for constellations.

In addition to the constellation myths, there are ancient and modern uses of constellations:
1. They helped ancient farmers know when to plant and harvest crops. Constellations can be used as a calendar in the sky.
2. Travelers use them to navigate from one place to another, relying on different stars to guide them on journeys throughout the world.
3. Modern astronomers and star gazers use them to help keep track of specific stars in the sky.
4. Astronomers use them to locate other objects in the sky such as galaxies or nebulae, which are areas where gas and dust are cluttered

We hope you and your kids enjoyed our constellation video and are able to identify some of the major constellations when you look up at the stars at night.

Finance and capital markets on Khan Academy: Interest is the basis of modern capital markets. Depending on whether you are lending or borrowing, it can be viewed as a return on an asset (lending) or the cost of capital (borrowing). This tutorial gives an introduction to this fundamental concept, including what it means to compound. It also gives a rule of thumb that might make it easy to do some rough interest calculations in your head.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
